    • The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure discloses a method for reporting channel state information CSI, including: determining, by a user equipment (UE), a number of resources occupied by a demodulation reference signal (DMRS) used when calculating CSI; determining, by the UE, a number of resources used to transmit a physical downlink shared channel (PDSCH) used when calculating the CSI according to the number of resources occupied by the DMRS; and calculating, by the UE, the CSI according to the number of resources used to transmit the PDSCH determined, and reporting the CSI. Using the present disclosure can guarantee the performance of transmitting PDSCHs in a NR system.
    • 本发明涉及将被提供用于支持更高数据速率的第五代(5G)或5G通信系统。第四代(4G)通信系统例如长期演进(LTE) )。 本发明公开了一种上报信道状态信息CSI的方法,包括:用户设备(UE)确定计算CSI时使用的解调参考信号(DMRS)占用的资源数量; 所述UE根据所述DMRS占用的资源数量,确定在计算CSI时使用的用于传输物理下行共享信道PDSCH的资源数量; UE根据用于传输所确定的PDSCH的资源数量计算CSI,并上报CSI。 使用本公开可以保证在NR系统中传送PDSCH的性能。
